Seven new prosapogenins have been isolated as their methyl esters [(1), (2), and (4)–(8)] from the roots of Platycodon grandiflorum A. DC., along with the known 3-O-β-D-glucopyranosylplatycodigenin methyl ester (3). The structures of the seven compounds were elucidated using 13C and 1H n.m.r. spectroscopy.
从Platycodon grandiflorum A. DC。的根中分离出七个新的prosapogenins作为它们的甲酯[(1),(2)和(4)–(8)] ,以及已知的3- O- β- D -吡喃葡糖基铂二糖苷甲酯(3)。使用13 C和1 H nmr光谱对7种化合物的结构进行了阐明。
